SPECIFICATION vforming' part of Letters Patent No. 699,548, dated. May 6, 17902.

Application led July 15, 1901.` Serial No. 68,333. (No model.)

To @ZZ whom t may concern:

Be it known that I, BENJAMIN F. D MILLER, a citizen of the United States, residing at lVooster, in the county of lVayne and State of Ohio, have invented new and useful lmprovements in Music-Leaf Turners, of which the following is .a specification.

My invention relates to music-leaf turners; and the object of the same is to improve the device for which Letters Patent'No. 463,529 were granted me. The several improvements consist, first, of means for turningl the frames by mechanism operated by the knees of the player; secondly, detachable means for connecting the device to the music-board, and, thirdly, of detachable means for securing the frames to the back. The novel construction by which this is accomplished is fully de` scribed in this specification and claimed, and illustrated in the accompanying drawings, forming a part thereof, in which- Figure lis an elevation of my device. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a detail perspective of the trigger mechanism. Fig. L.tis an elevation ofa piano with my device attached thereto. Fig. 5 is a detail fragment showing the crank-arms and sheaves. Fig. 6 is a detail perspective showing one of the spring-actuated levers. Fig. 7 is a detail perspective of the inclined axle.

Like numerals of reference designate like parts in thediierent views of the drawings.

The numeral 1 designates a music-board of an upright piano. Mydevice is supported by this music-board 1, and'tosupply means for attaching it thereto U-shaped brackets 4:'

. are rigidly secured to the front face ofthe board 1, one near the top and the othernear the bottom. The brackets L1 are each provided with two apertures 5 and 6, round and; square, respectively, for a purpose which willappear.

The back frame of my music-holder is des-f ignated by the numeral 7 and is, in the main,-` of the usual construction, being formed ofy vertical side bars 8 and a center bar 9 andy pivoted horizontal bars 10. Rubber bumpers 11 are, secured to the bars 8. The center bar 9 is formed of "two nesting flanged sections 9- and 9", and formed integral with the rear section 9b are two casings 10 and 11.

cured to the center bar 9.

,14, connecting the catches 13, and a key 15,

mounted on theforward side of the'casing and having a shank 16 extending thereinto and bearing a hollow cross-bar 17, through which the cord 14 passes. By this arrangement the catches 13 can be operatediand disengaged by simply turning the key l5.

As in my former device above referred to, aseries of hinged brackets or frames 18 are used and pivoted to an inclined axle 19, se-

The frames 18 are each `provided with gravity-catches 2O and operated by arms 2l, bearing beveled lugs 22 and pivoted to upturned feet 22a on the lower end of the bar 9. The arms 2l are provided with sheaves 24. integral therewith, and rigid arms 25, secured to the frame, serve as Stops to limit the backward swing of the arms. Springs 23, surrounding the pivots, serve to return the arms to their initial positions after displacement. The lugs 22 are designed to engage thelframes 18 to turn them over. Cords 26 pass around the sheaves 23 and are oppositely connected to crank-arms 27 on angular shafts 28, passing through apertures 28' in the music-board 1. The shafts 28 are turned by means of lever-arms 29, having vhubs 30 integral therewith and fitting over said shafts 28. The shafts 28 are inclosed in -housings'31 and provided with flanges 32.

Stiff spiral springs surround the hubs 30 and are secured to an ear 33 and to the levers 29. The ianges 32 serve to coniine the springs.

The outer ends of the lever-arms 29 engage kand through the casingvof thepiano and are connected to levers 36, pivoted tothe box of the piano beneath the keyboard. The levers 3G are constructed to be operated by the knees of the player to pull the cords to operate the lever-arms 29 to operate the arms 2l to fold over the frames 18, carrying the leaves of music.

The axle l0 is made detachable from the back for convenience in attaching leaves of music to the frames IS. This is accomplished by means of parallel guides 37, mounted on the bar 9, with an intervening space 3S. Gppositely-extending tongues 39, rigid on the axle l5), are constructed to slip under the guides 37, which extend on each side of the axle, and thus securely hold the axle in place. To remove the axle, it is moved longitudinally upward, and thereby disengaged from the guides 37.

As the function and relation of each ot the parts have been fullyset forth, no further description of operation is deemed necessary.

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

Having described my invention, what I claim as new, and Wish to secure by Letters Patent, is-

l. In a music-turner the combination with a back frame having a center bar, of lugs projecting from the back of said bar, notched spring-actuated catches located adjacent to said lugs, a cord connecting said catches, and a key having` a longitudinally-apertured cross-bar which is threaded on said cord, said key being constructed to be turned to tighten said cord to operate said catches, substan-r tially as described.

2. In a music-turner, the combination with a music-board bearing apertured U-shaped brackets, of a back frame having a center bar, of lugs projecting `from said center bar and constructed to tit said apertures in said brackets, of pivoted spring-actuated catches constructed to engage apertures in said brackets, a cord connecting said catches, and a ke)v connected to said cord and constructed to be operated to disengage said catches, substantially as described.

3. In a music-leaf turner, the combination with a music-board bearing icl-shaped brackets having apertured cross-bars, of a back frame, spring actuated notched catches mounted on said back and located to engage said apertures in said brackets, a cord connecting` said catches, and means for tightening said cord to operate said catches to dis engage them from 'said brackets, substantially as described.

4. In a music-turner, the combination with frames for supporting music and constructed to be folded over, of spring-actuated arms bearing sheaves and constructed to engage said frames, angular shafts bearing crankarms7 cords passing around said sheaves and connected to said crank-arms,springactuated lever-arms mounted on said angular shafts, levers arranged to be operated by the knees of the player to turn the said frames, cords connected to said lever-arms and to said knee-operated levers, substantially as described.

5. In a music-turner, the combination with a back, of parallel guides mounted on said back with an intervening space, of au axle bearing folding frames, oppositely-extcnding ears mounted on said axle and constructed to [it under said guides and hold the axle in place, said ears being located in substantially the same pla-ne with said shaft, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
